背景技术
为解决终端在空闲(idle)态和非激活(inactive)态接收寻呼的功耗问题，3GPP引入了寻呼提前指示(paging early indication，PEI)，PEI中的寻呼指示(paging indication，PI)域用于指示寻呼帧(paging frame，PF)中的寻呼时机(paging occasion，PO)对应的终端，或者PO对应的终端子组中的终端是否监听寻呼消息。然而，当前协议中并没有规定将PF中的PO，或者PO中的不同终端子组映射到PI域中的方式，导致PEI所需要的比特数可能较多。当PEI的比特数较多时，可能会影响PEI的接收性能、以及PEI的使用范围。因此，如何使PEI的比特数在一个合理的范围之内，是一个亟待解决的问题。

图1示出了本申请实施例适用的通信系统100，该通信系统100中包括终端设备和网络设备。
本申请实施例中的终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备，未来6G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。

为解决终端在空闲态和非激活态接收寻呼的功耗问题，3GPP引入了一种新的寻呼指示信息，也可以称为寻呼早期指示(paging early indication，PEI)或者高级寻呼指示(advanced paging indication)，寻呼指示信息一般可能包括以下三种指示域：
1：寻呼指示域(paging indication field)，简称PI域，用于指示PF中的PO对应的终端，或者PO对应的终端子组中的终端是否监听需要寻呼消息。
2：跟踪参考信号(tracking reference signal，TRS)域，用于指示空闲/非激活态是否有可用的TRS资源，该TRS资源可以为处于空闲/非激活态的终端提供时频偏估计增强。
3：短消息域(short message field)，用于指示系统消息是否发生变更，或者提供地震、海啸等突发事件预警等信息。
下面通过一个例子说明现有技术存在的不足。
假设一个PEI关联2个PF，每个PF包括4个PO，每个PO上的终端被分成8个子组，如果基于PI域中的比特与终端子组一一对应的映射方式，则PI域需要64个比特。作为对比，寻呼物理下行控制信道(physical downlink control channel，PDCCH)的下行控制信息(downlink control information，DCI)的大小一般为41比特。此时，PEI中仅PI域的比特数已经超过了寻呼PDCCH的DCI的比特数，如果再考虑TRS域和短消息域所占的比特数，PEI的比特数会更多。在PEI的比特数过多的情况下，PEI的接收性能会降低，PEI的使用范围也会受到影响。
基于此，本申请提供了多种方法，用于解决上述问题。下面对本申请提出的方案进行 详细介绍。为了方便描述，下文以网络设备为基站、终端设备为UE、寻呼指示为PEI为例进行说明。
图2示出了本申请提供的一种通信方法200。该方法200包括：
S210，基站#1根据第一PEI关联的所有PO的个数(记为W)和第一PEI中PI域的比特数(记为L)，确定第一PEI关联的所有PO中每个PO包括的子组数(记为K)。
应理解，当N的取值为1时，表示一个PO中的UE不进行分组。
作为一种可能的方式，N可以通过下述公式确定：
Figure PCTCN2022129572-appb-000001
其中，
Figure PCTCN2022129572-appb-000002
的含义为L/W向下取整。
作为另一种可能的方式，N可以通过下述公式确定：
Figure PCTCN2022129572-appb-000003
其中，K max表示K可以取的最大值，例如K max＝8。
例如，第一PEI中PI域的比特个数为16，第一PEI关联的PO的个数为8，则N为2。即，第一PEI关联的8个PO中，每个PO对应的UE被分成2个子组。
又例如，第一PEI中PI域的比特个数为16，第一PEI关联的PO的个数为2，则N为8。即，第一PEI关联的8个PO中，每个PO对应的UE被分成8个子组。
对于第一PEI关联的所有PO的个数而言，可选地，作为一种方式，可以直接在基站#1中预配置第一PEI关联的所有PO的个数。
可选地，作为另一种方式，可以在基站#1中预配置第一PEI关联的PF的个数、以及每个PF包括的PO的个数。此时，基站#1可以根据第一PEI关联的PF的个数、以及每个PF包括的PO的个数确定第一PEI关联的所有PO的个数。
在一般情况下，第一PEI关联的所有PO的个数＝第一PEI关联的PF的个数乘以每个PF包括的PO的个数；例如，第一PEI关联2个PF，每个PF包括4个PO，则基站#1确定第一PEI关联8个PO。
对于第一PEI中PI域的比特数而言，可选地，作为一种方式，可以在基站#1中预配置第一PEI中PI域的比特数。
可选地，作为另一种方式，PI域的比特数与第一PEI关联的所有PO的个数相关。具体地，在第一PEI关联的所有PO的个数小于或等于第一值的情况下，PI域的比特数为第二值；在第一PEI关联的所有PO的个数大于第一值的情况下，PI域的比特数为第三值，第三值大于第二值。
一示例，第一PEI关联的PO的个数小于或等于4(或者，第一PEI仅关联一个PF)，则基站#1确定第一PEI中PI域的比特个数可以为8或者16。
又一示例，第一PEI关联的PO的个数大于4，例如为8个PO，(或者，第一PEI关联多个PF，如2个PF)，则基站#1确定第一PEI中PI域的比特个数为32。
应理解，第一PEI中PI域的比特个数可以有多个档位，多个档位对应多个数值。当第一PEI关联的PO的个数越多时，基站#1可以选择档位越高的数值作为第一PEI中PI域的比特个数。
此外，第一PEI中PI域的比特数可以小于或等于特定阈值。可选地，该特定阈值与寻呼PDCCH的DCI的比特数相关联。该特定阈值的取值可以为提前约定的，或者预配置 到基站#1中的。
例如，寻呼PDCCH的DCI通常为41个比特，则该特定阈值可以为32。
关于该特定阈值，下文不再赘述。
S220，UE#1根据第一PEI关联的所有PO的个数和第一PEI中PI域的比特数，确定目标比特在第一PEI的PI域中的位置。
应理解，该目标比特用于指示UE#1是否监听寻呼消息。
作为一种可能的方式，UE#1可以确定UE#1所属的目标PO。例如，UE#1可以根据UE#1的标识(UE#1的ID)确定目标PO的索引。
进一步地，UE#1可以根据第一PEI关联的所有PO的个数和第一PEI中PI域的比特数，确定第一PEI关联的所有PO中每个PO包括的子组数。
再进一步地，UE#1根据第一PEI关联的所有PO中每个PO包括的子组数，确定UE#1在目标PO中的目标子组。例如，UE#1可以根据第一PEI关联的所有PO中每个PO包括的子组数，并结合UE#1的ID，确定该目标子组的索引。
示例1，如果第一PEI关联的所有PO中每个PO包括的子组数为2，UE#1确定UE#1属于目标PO中的子组#1。
示例2，如果第一PEI关联的所有PO中每个PO包括的子组数为8，UE#1确定UE#1属于目标PO中的子组#2。
由上述两个示例可知，UE#1所属的目标子组可能随着每个PO包括的子组数的不同而不同。
作为一种可能的方式，目标子组的索引可以通过下述公式确定：假设第一PEI关联了N个PF，每个PF包括M个PO(或者第一个PEI关联了W个PO，W＝N×M)，每个PO包括K个子组。
index＝(n-1)×M×K+(m-1)×K+k。
其中，目标子组属于N个PF的第n个PF、第n个PF的第m个PO、第m个PO的第k个子组，k＝(UE_IDmodK)+1。n、m、k均从1开始计数。
UE可以确定目标PO子组对应于PI域中的第index个比特(k从1开始计数)
如果目标子组的PF索引n、PO索引m、在每个PO中的PO子组索引k均从0开始计数，则类似的可以得到目标子组的索引为：
index＝n×M×K+m×K+k
该目标子组将由PEI中PI域的第index个比特指示是否存在寻呼。
进一步地，UE#1根据UE#1所属的目标PO以及目标子组，确定目标比特在第一PEI的PI域中的位置。
S230，基站#1根据第一PEI关联的所有PO中每个PO包括的子组数，确定第一PEI的PI域中每个比特的比特值。
其中，第一PEI中PI域包括的比特数与第一PEI关联的所有PO包括的子组总数相同。即，第一PEI中PI域包括的多个比特与第一PEI关联的所有PO包括的子组一一对应(记为第二映射方式，所谓“映射”即指：如果一个子组映射到PI域的某一比特，则该比特用于指示该子组上是否存在寻呼)。
比特值可以为“0”或“1”。当某一比特的比特值为“0”时，指示该比特所对应的子组不存 在寻呼消息；当某一比特的比特值为“1”时，指示该比特所对应的子组存在寻呼消息。
下面对第二映射方式进行说明。
方式1：
按照先PF，后PO，最后PO中的子组的顺序映射。
例如，可以先映射第一个PF的所有PO中的所有子组，再映射第二个PF的所有PO中的所有子组；以此类推完成对PEI对应的所有PF映射到PI域中，该映射为PF升序映射。或者可以采用PF降序映射，先映射最后一个PF的所有PO中的所有子组，再映射倒数第二个PF的所有PO中的所有子组，以此类推完成对PEI对应的所有PF映射到PI域中。
对每个PF中的所包括PO而言，可以先映射第一个PO中的所有PO子组，再映射第二个PO中的所有PO子组，以此类推完成对每个PF对应的所有PO映射到PI域中，该映射为PO升序映射。或者可以采用PO降序映射，该方法和PF降序映射类似，不再复述。例如，第一PEI关联2个PF(记为PF#1和PF#2)，每个PF包括2个PO(分别记为PO#1、PO#2、PO#3、PO#4)，每个PO包括2个子组(分别记为子组#1至子组#8)。
那么，可以先映射PF#1的PO#1的子组#1和子组#2，再映射PF#1的PO#2的子组#3和子组#4，再映射PF#2的PO#3的子组#5和子组#6，再映射PF#2的PO#4的子组#7和子组#8。
方式2：
对于一个PF而言，可以先映射该PF所有PO中的第一个子组，再映射该PF所有PO中的第二个子组，以此类推；或者，先映射该PF所有PO中的最后一个子组，再映射该PF所有PO中的倒数第二个子组，以此类推。
对于一个PF包括的所有PO而言，可以先映射所有PO中的第一个PO，再映射所有PO中的第二个PO，以此类推；或者，先映射所有PO中的最后一个PO，再映射所有PO中的倒数第二个PO，以此类推。
对于多个PF而言，可以先映射多个PF中的第一个PF，再映射多个PF中的第二个PF，以此类推；或者，先映射多个PF中的最后一个PF，再映射多个PF中的倒数第二个PF，以此类推。
显然，第二映射方式还可以包括其他类似的映射方式(例如PF，PO和PO子组映射先后顺序不同，或者混合采用升序或者降序的映射方式)，本申请对此不予限制。
此外，作为一种情况，基站可以通过信令或消息，通知UE将不同子组映射到PI域中的方式。作为另一种情况，基站和UE可以通过协议预定义将不同子组映射到PI域中的方式。换句话说，UE也可以获知基站将不同子组映射到PI域中的方式。在S220中，UE可以根据响应的映射方式，确定目标比特在PI域中的位置。
应理解，基站#1还可以确定TRS域和短消息域的比特取值，最终生成第一PEI。
S240，基站#1发送第一PEI。相应地，UE#1接收第一PEI。
作为一种可能的方式，基站#1可以通过广播/组播的方式发送第一PEI。
S250，UE#1根据第一PEI以及目标比特，确定是否监听寻呼消息。
例如，UE#1目标PO为PO#1，目标子组为PO#1对应的子组#11，基站基于S230中的方式1将不同子组映射到PI域中，则目标比特为比特#1。UE#1根据比特#1确定是否监 听寻呼消息。如果比特#1取“1”，则UE#1监听寻呼消息；如果比特#1取“0”，则UE#1不监听寻呼消息。
根据本申请的方案，基站#1根据PI域的比特数以及一个PEI关联的PO的个数，确定每个PO包括的子组数。相比而言，如果基站#1根据一个PEI关联的PF的个数、每个PF包括的PO的个数、每个PO包括的子组数，确定PI域的比特数，就可能导致PI域的比特数过多。因此，采用本申请的方案，不会出现PI域的比特数过多的情况，从而确保PEI以较好的性能接收。
可选地，在S220之前，该方法200还包括S260：
S260，基站#1向UE#1发送第一信息和第二信息。相应地，UE#1接收第一信息和第二信息。
第一信息指示第一PEI关联的所有PO的个数，或者第一PEI关联的PF的个数；第二信息指示第一PEI中PI域的比特数。
作为一种可能的方式，基站#1可以通过广播/组播的方式向UE#1发送第一信息和第二信息。
图3示出了本申请提供的一种通信方法300。该方法300包括：
S310，基站#1根据第一PEI关联的所有PO的个数和第一PEI关联的所有PO中每个PO包括的子组数，确定第一PEI关联的所有PO包括的子组总数(记为Q)。
例如，第一PEI关联2个PF，每个PF包括4个PO，每个PO包括8个子组，则第一PEI关联的所有PO包括的子组总数Q＝2×4×8＝64。
S320，UE#1根据第一PEI关联的所有PO的个数和第一PEI关联的所有PO中每个PO包括的子组数，确定第一PEI关联的所有PO包括的子组总数。
具体的方法，可以参考S310中的描述。
S330，在上述子组总数大于特定阈值的情况下，基站#1基于第一映射方式确定第一PEI的PI域中每个比特的比特值，第一映射方式为至少两个子组映射到该PI域中同一比特的映射方式。
应理解，该特定阈值可以为提前约定的，或者预配置到基站#1中的。
下面通过多个示例对第一映射方式进行说明。
示例1：
对于同一PO，将同一PO对应的多个子组中的至少两个子组映射到第一PEI的PI域的同一比特。
例如，第一PEI关联的8个PO，每个PO对应的UE被分成的8个子组，特定阈值为32。即，子组总数为64，大于该特定阈值。此时，第一PEI的PI域可以包括16个比特(记为，比特#1-比特#16)。对于8个PO中的PO#1而言，PO#1的子组#11-子组#14映射到PI域中的比特#1，子组#15-子组#18映射到PI域中的比特#2。对于PO#2而言，PO#2的子组#21-子组#24映射到比特#3，子组#25-子组#28映射到比特#4。以此类推，在此不再一一描述。
由上可知，如果64个子组与第一PEI的PI域中的多个比特一一对应的话，PI域需要64个比特。基于本申请的方案，仅仅需要16个比特，因此可以节省PI域的比特数目。
示例2：
对于不同PF，将不同PF的PO中的至少两个子组映射到第一PEI的PI域的同一比特。
例如，第一PEI关联2个PF(记为PF#1和PF#2)，每个PF包括4个PO(分别记为PO#11-PO#14，PO#21-PO#24)，每个PO对应的UE被分成的子组个数N＝8(分别记为子组#111-子组#118，子组#121-子组#128，子组#131-子组#138，子组#141-子组#148，子组#211-子组#218，子组#221-子组#228，子组#231-子组#238，子组#241-子组#248)，特定阈值为32。即，子组总数为64，大于该特定阈值。此时，可以将PO#11对应的子组#111和子组#112，以及PO#21对应的子组#211和子组#212映射到PI域的比特#1；将PO#11对应的子组#113和子组#114，以及PO#21对应的子组#213和子组#214映射到比特#2。以此类推。即，PI域只需16个比特。
示例3：
对于不同PF，将不同PF的PO中子组索引相同的PO子组映射到第一PEI的PI域的同一比特。
例如，第一PEI关联4个PF(记为PF#1，PF#2，PF#3和PF#4)，每个PF包括4个PO(分别记为PO#11-PO#14，PO#21-PO#24，PO#31-PO#34，PO#41-PO#44)，每个PO对应的UE被分成的子组个数为4(分别记为子组#111-子组#114，子组#121-子组#124，子组#131-子组#134，子组#141-子组#144，子组#211-子组#214，子组#221-子组#224，子组#231-子组#234，子组#241-子组#244，子组#311-子组#314，子组#321-子组#324，子组#331-子组#334，子组#341-子组#344，子组#411-子组#414，子组#421-子组#424，子组#431-子组#434，子组#441-子组#444)，特定阈值为32。即，子组总数为64，大于该特定阈值。此时，可以将PF#1和PF#3中PO索引和PO子组索引相同的PO子组映射到同一比特，将PF#2和PF#4中PO索引和PO子组索引相同的PO子组映射到同一比特，例如PF#1中PO#11的子组#111和PF#3中PO#31的子组#311，映射到PI域的比特#1；将PF#1中PO#11的子组#112和PF#3中PO#31的子组#312，映射到PI域的比特#2。以此类推。即，PI域只需32个比特。
示例4：
采用循环余数映射的方式进行映射。
假设一个PEI关联A个PF，每个PF包括B个PO，每个PO对应的UE被分成C个子组。
对于一个子组，如果该子组对应的PF的索引、PF中PO的索引、该子组的索引分别为a、b、c，则该子组的编号(index)可以通过下述公式计算。
index＝(a-1)×B×C+(b-1)×C+c。
例如，一个PEI关联2个PF，每个PF包括4个PO，每个PO对应的UE被分成8个子组。即，A＝2、B＝4、C＝8。
对于第1个PF包括的第1个PO中的第1个子组，该子组的index＝(1-1)×4×8+(1-1)×8+1＝1。如果PI域的比特数最大可以为L max(例如L max为20)，由于[(index-1)modL max]+1＝1，则将该子组映射到该PI域中第1个比特。
应理解，本申请中xmody的含义为：x除以y的余数。
对于第1个PF包括的第3个PO中的第4个子组，该子组的index＝(1-1)×4×8+(3-1)×8+4＝20。如果PI域的比特数最大可以为L max(例如L max为 20)，由于[(index-1)modL max]+1＝20，则将该子组映射到该PI域中第20个比特。
对于第2个PF包括的第3个PO中的第4个子组，该子组的index＝(2-1)×4×8+(3-1)×8+4＝52。如果PI域的比特数最大可以为L max(例如L max为20)，由于[(index-1)modL max]+1＝12，则将该子组映射到该PI域中第12个比特。
需要说明的是，上述循环余数映射中，PF的索引、PF中PO的索引、该子组的索引a、b、c均采用从1开始计数的方式，
如果a、b、c均采用从0开始计数，同理可以得到子组的编号(index)为index＝a×B×C+b×C+c，并且标号为index的子组将由PI域中第indexmodL max比特来指示是否存在寻呼。
应理解，基站#1还可以确定TRS域和短消息域的比特取值，最终生成第一PEI。
S340，在上述子组总数大于特定阈值的情况下，UE#1基于第一映射方式确定目标比特在第一PEI的PI域中的位置。
应理解，该特定阈值可以为提前约定的，或者预配置到UE#1中的，或者UE#1从基站#1获取的，不予限制。该特定阈值可以为第一PEI中PI域的比特数，或者大于第一PEI中PI域的比特数。
具体地，UE#1可以确定UE#1所属的目标PO，以及在目标PO中的目标子组。
进一步地，UE#1根据UE#1所属的目标PO、以及目标子组，并基于第一映射方式确定目标比特在第一PEI的PI域中的位置。
例如，第一映射方式如S330中示例1，如果UE#1所属的目标PO为PO#1，目标子组为PO#1对应的子组#11，则该目标比特为比特#1。即，该目标比特的位置为PI域中的第一个比特。
S350，基站#1发送第一PEI。相应地，UE#1接收第一PEI。
S360，UE#1根据第一PEI以及目标比特，确定是否监听寻呼消息。
例如，UE#1确定该目标比特为比特#1，UE#1解析第一PEI的PI域中的比特#1。如果比特#1取“1”，则UE#1监听寻呼消息。如果比特#1取“0”，UE#1不监听寻呼消息。
根据本申请的方案，如果子组总数大于特定阈值，则基站#1基于第一映射方式确定PI域中每个比特的比特值，换句话说，基站#1基于第一映射方式生成PEI，该PEI的PI域的比特数小于或等于该特定阈值。因此，采用本申请的方案，不会出现PI域的比特数过多的情况，从而确保PEI以较好的性能接收。
可选地，作为另一种可能的情况，该方法300不包括S330和S340，在S350之前该方法300还包括S370和S380：
S370，在上述子组总数小于或等于特定阈值，或者该特定阈值不存在的情况下，基站#1基于第二映射方式确定第一PEI的PI域中每个比特的比特值。
该第二映射方式为第一PEI关联的所有PO包括的子组与PI域中的多个比特一一对应的映射方式。
具体地，该第二映射方式可以参考S230中的描述。在此不再赘述。
S380，在多个子组的子组总数小于或等于特定阈值，或者该特定阈值不存在的情况下，UE#1基于第二映射方式确定目标比特在第一PEI的PI域中的位置。
根据本申请的方案，基站#1可以根据子组总数选择合适的映射方式生成PEI，使得 PEI中PI域的比特数不会过多，从而确保PEI以较好的性能接收。
可选地，在S320之前，该方法300还包括S390：
S390，基站#1发送第一信息和第三信息。相应地，UE#1接收第一信息和第三信息。
第一信息指示第一PEI关联的所有PO的个数，或者第一PEI关联的PF的个数；第三信息指示第一PEI关联的所有PO中每个PO包括的子组数。
图4示出了本申请提供的一种通信方法400。该方法400包括：
S410，在一个SSB周期包括多个PF的情况下，基站#1生成多个PEI，该多个PEI与多个PF对应。
可选地，作为一种方式，多个PEI与多个PF可以是一一对应的关系。即，PEI的个数与PF的个数相同。
可选地，作为另一种方式，一个PEI可以对应多个PF。例如，一个SSB周期包括4个PF，PEI#1对应PF#1和PF#2，PEI#2对应PF#3和PF#4。
S420，UE#1根据目标PF、以及多个配置信息与多个PF的对应关系，确定目标PEI的配置信息。
应理解，该目标PF为多个PF中的一个。
例如，目标PF为PF#1，则UE#1从多个配置信息与多个PF的对应关系中，确定PF#1所对应的目标PEI的配置信息。
作为一种可能的方式，可以在UE#1中预配置该多个配置信息、以及该多个配置信息与多个PF的对应关系。
下面对多个配置信息进行说明。
情况1：
多个配置信息包括多个RNTI的信息。多个PEI与多个RNTI一一对应，即，每个PEI配置的RNTI均可以不同。
情况2：
多个配置信息包括多个搜索空间集(search space set)的信息。多个PEI与多个search space set一一对应，即，每个PEI的搜索空间集配置也可以不同。
情况3：
多个配置信息包括相同的搜索空间集、以及多个初始监听时机(firstPDCCH-MonitoringOccasionOfPEI)的信息，多个PEI与多个初始监听时机一一对应，多个PEI对应的监听时机互不重叠，即，每个PEI配置的初始监听时机可以不同。
作为一种可能方式，假设，一个SS突发集中包括4个SSB，一个SSB周期包括2个PF，每个PF包括2个PO。那么，一个PF包括的每个PO中包括4个MO，该4个MO与4个SSB一一对应。
此时，可以通过2个PEI来与2个PF对应。其中，PEI#1用于指示UE是否监听PF#1，PEI#2用于指示UE是否监听PF#2。
为了区分PEI#1和PEI#2的监听时机，PEI#1的初始监听时机可以配置为搜索空间集中的第K个监听时机；PEI#2的初始监听时机可以配置为搜索空间集中的第K+4个监听时机。因此，2个PEI对应的监听时机互不重叠。
S430，基站#1发送多个PEI。
S440，UE#1根据目标PEI的配置信息，接收目标PEI。
应理解，目标PEI为多个PEI中的一个PEI。
S450，UE#1根据目标PEI，确定是否监听目标PF。
应理解，目标PF与目标PEI是对应的。
应理解，UE#1只需解析目标PF的目标PO的目标子组所对应的目标比特，可以不解析PI域中的其他比特。
根据本申请的方案，如果一个SSB周期包括多个PF，则可以为多个PF配置多个PEI，使得多个PEI中每个PEI的PI域的比特数不会过多，从而确保PEI以较好的性能接收。
可选地，在S420之前，该方法400还包括S460：
S460，基站#1向UE#1发送第四信息。相应地，UE#1接收第四信息。
第四信息包括多个配置信息，该多个配置信息用于配置多个PEI。
可选地，第四信息中还包括多个配置信息与多个PF的对应关系。
此外，作为一种特殊的情况，一个SSB周期包括多个PF，但是多个PF对应的多个PEI的配置信息相同(例如，多个PEI对应的RNTI相同、监听时机相同)。此时，该多个PEI其实可以通过一个PEI PDDCH发送。即，通过一个PEI指示多个PF上是否存在寻呼，并且不同PF上的PO的PO子组将映射到相同的目标比特上。具体可以参考S330的描述，在此不再赘述。
图5示出了本申请提供的一种通信方法500。该方法500包括：
S510，UE#1向网络设备发送第五信息。相应地，网络设备接收第五信息。
例如，UE#1可以在建立RRC连接的过程中，或者在建立RRC连接之后，向网络设备发送第五信息。
作为一种情况，UE#1可以向核心网设备发送第五信息。
下面对第五信息进行说明。
方式1：
第五信息直接指示在接收寻呼PDCCH之前需要接收SS突发集的个数。
例如，第五信息包括L的取值为2的信息。
方式2：
第五信息指示UE#1为接收寻呼PDCCH需要提前唤醒的时长。UE#1在该时长需要进行以下操作中的一项或多项：
时频跟踪、自动增益控制(automatic gain control,AGC)、SIR估计、波束测量。
应理解，当基于方式2进行时，网络设备在接收到第五信息后，可以间接计算出UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数。
S520，核心网设备向接入网设备发送该第八信息。相应地，接入网设备接收第八信息。
该第八信息所表达的含义与第五信息相同。
例如，第八信息直接指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数。或者，第八信息指示UE#1为接收寻呼PDCCH需要提前唤醒的时长。
应理解，在需要寻呼UE#1的情况下，核心网设备还可以向接入网设备发送UE#1的寻呼消息。
S530，接入网设备根据第八信息，确定发送UE#1对应的PEI(记为PEI#1)的时机。
下面介绍接入网设备根据第八信息，确定发送PEI#1的时机的方式。
方式1：
例如，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为1，则接入网设备在发送寻呼PDCCH之前的第一个SS突发集(SS burst)之后发送PEI#1。
又例如，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为2，则接入网设备在发送PDCCH之前的第二个SS突发集与第一个SS突发集之间发送PEI#1。
又例如，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为3，则接入网设备在发送PDCCH之前的第三个SS突发集与第二个SS突发集之间发送PEI#1。
方式2：
接入网设备根据第八信息，确定发送PEI#1的时机到发送UE#1需要接收的寻呼PDCCH的时机之间的时间间隔应大于或者等于时间偏移(Time_offset)，所述Time_offset是一个和UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数有关的时间量，例如Time_offset可以通过以下公式中的一个计算得到：。
公式1：Time_offset＝mini_gap+(L-1)*SSB_periodicity
公式2：Time_offset＝(L-1)*SSB_periodicity
公式3：Time_offset＝max[mini_gap,(L-1)*SSB_periodicity]
其中，mini_gap表示发送PEI与发送寻呼PDCCH之间的最小时间间隔；L表示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数，SSB_periodicity表示SS突发集的发送周期，一般为20ms，40ms，80ms或者160ms等；“*”表示相乘。
例如，如图6中的(a)所示，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为1，如果按照公式1计算，则发送PEI#1的时机与发送寻呼PDCCH的时机之间的时间间隔应大于或者等于mini_gap。
应理解，接入网设备可以获知发送寻呼PDCCH的时机。
又例如，如图6中的(b)所示，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为2，如果按照公式2计算，则发送PEI#1的时机与发送寻呼PDCCH的时机之间的时间间隔应大于或者等于一个SSB_periodicity。
又例如，如图6中的(c)所示，第八信息指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数为3，如果按照公式3计算，则发送PEI#1的时机与发送寻呼PDCCH的时机之间的时间间隔应大于或者等于mini_gap与2*SSB_periodicity之间的较大值。
可选地，作为一种方式，该方法可以不包括S530，在S520中，核心网设备可以确定发送PEI#1的时机，并通知接入网设备发送PEI#1的时机。其中，核心网设备确定发送PEI#1的方式可以参考S530中的方式1和方式2。即，由核心网设备执行S530中接入网设备的操作。
可选地，UE#1可以直接向接入网设备发送第五信息，而不是通过核心网设备向接入网设备发送第八信息。
S540，UE#1根据第五信息，确定接入网设备发送PEI#1的时机。
该过程与S530类似，即，由UE#1执行S530中接入网设备的操作。
S550，接入网设备在发送PEI#1的时机，发送PEI#1。相应地，UE#1在发送PEI#1的时机，监听PEI#1。
根据本申请的方案，当不同UE上报的L值不同时，接入网设备可以根据不同的L值，确定发送不同UE对应的PEI的时机。相比而言，如果不区分UE的L值，接入网设备发送PEI时可能无法达到节省功耗的最佳效果。因此，采用本申请的方案，接入网设备根据UE上报的L值，确定每个UE对应的PEI的发送时机，从而可以更好地节省功耗。
图7示出了本申请提供的一种通信方法700。该方法700包括：
S710，接入网设备发送第六信息，该第六信息指示发送PEI#1的时机在目标PO之前的第N个SS突发集之后。相应地，UE#1接收第六信息。
N为正整数，例如，N为1、2或者3。
该N的取值可以视为目标小区中的UE确定PEI的发送时机所采用的默认值。该目标小区为该接入网设备所属的小区。
例如，接入网设备可以在系统消息中携带该第六信息，并且采用广播的方式发送该第六信息。
应理解，该目标小区为接入网设备所属的小区。
S720，接入网设备根据第六信息，确定发送UE#1对应的PEI(记为PEI#1)的时机。
该过程与S530类似，即，将S530中的第五信息替换为第六信息。
S730，UE#1根据第六信息，确定接入网设备发送PEI#1的时机。
该过程与S530类似，即，由UE#1执行S530中接入网设备的操作。
S740，接入网设备在发送PEI#1的时机，发送PEI#1。相应地，UE#1在发送PEI#1的时机，监听PEI#1。
根据本申请的方案，UE也可以不上报自身的L值，通过从接入网设备接收第六信息，确定监听PEI的时机。
可选地，作为一种情况，该方法700适用于UE#1首次开机驻留到目标小区的场景。
可选地，作为另一种情况，该方法700适用于由于UE#1的位置不固定，UE#1经常移动，并且从源小区移动(切换)到了目标小区的场景。
可选地，作为一种情况，该方法700可以在方法500之前执行。即，方法500与方法700之间并不是孤立的，二者可以结合在一起使用。
例如，当UE#1首次开机驻留到目标小区时，UE#1可以基于方法700监听PEI#1，后续，UE#1可以基于方法500监听PEI#1。
应理解，方法500和方法700以UE#1为例，对本申请提出的方案进行了详细的说明。对于其他的UE，例如UE#2和UE#3，可以按照类似的方法进行。即，可以将方法500和方法700中的UE#1替换为其他UE。
图8示出了本申请提供的一种通信方法800。该方法800包括：
S810，多个UE向网络设备发送多个第五信息，该多个第五信息与该多个UE一一对应。相应地，网络设备接收该多个第五信息。
例如，该多个UE可以在进行RRC连接的过程中，或者在RRC连接建立之后向网络设备发送多个第五信息。
作为一种情况，多个UE可以向核心网设备发送多个第五信息。
应理解，该多个UE可以为同一目标小区中的多个UE，也可以是包含了多个小区的跟踪区域(tracking area，TA)中的多个UE。该目标小区为接入网设备所属的小区。
该多个第五信息中的每个第五信息用于指示所对应的UE在接收寻呼PDCCH之前需要接收SS突发集的个数(记为，L)。
例如，该多个第五信息为信息#A、信息#B、信息#C、信息#D，信息#A指示UE#1在接收寻呼PDCCH之前需要接收SS突发集的个数，信息#B指示UE#2在接收寻呼PDCCH之前需要接收SS突发集的个数，信息#C指示UE#3在接收寻呼PDCCH之前需要接收SS突发集的个数，信息#D指示UE#4在接收寻呼PDCCH之前需要接收SS突发集的个数。
或者，多个第五信息中的每个第五信息指示所对应的终端设备为接收寻呼PDCCH需要提前唤醒的时长。
S820，核心网设备向接入网设备发送该多个第九信息。相应地，接入网设备接收该多个第九信息。
该多个第九信息所表达的含义与该多个第五信息相同。
例如，该多个第九信息中的每个第九信息用于指示所对应的UE在接收寻呼PDCCH之前需要接收SS突发集的个数(记为，L)。或者，多个第九信息中的每个第九信息指示所对应的终端设备为接收寻呼PDCCH需要提前唤醒的时长。
核心网设备可以向一个接入网设备发送该多个第九信息，也可以向跟踪区域内的多个接入网设备发送该多个第九信息。
应理解，当一个UE被寻呼时，核心网设备还需要向接入网设备发送该UE的寻呼消息。
例如，当UE#1被寻呼时，核心网设备向接入网设备发送UE#1的寻呼消息。
S830，接入网设备根据该多个第九信息，确定发送寻呼指示的时机在目标寻呼时机之前的第N个SS突发集之后，N为正整数。
作为一种可能的方式，接入网设备可以确定多个UE对应的多个L值中出现次数最多的L值，N的取值可以为该出现次数最多的L值。
例如，10个UE中，L取值为2出现的次数最多，则N的取值为2。
作为另一种可能的方式，当多个UE中超过第一阈值个UE对应的在L值均为特定值，则N的取值等于该特定值。
例如，10个UE中超过8个UE对应的L值均为2个，则N的取值为2。
作为另一种可能的方式，接入网设备确定多个UE对应的L值的平均值，并确定N的取值等于该平均值。
例如，如下表所示，接入网设备确定N的取值为2。
表1
UE L值
UE#1 1
UE#2 2
UE#3 3
平均值 2
可选地，作为一种方式，该方法可以不包括S830，在S820中，核心网设备可以根据该多个第五信息确定发送寻呼指示的时机在目标寻呼时机之前的第N个SS突发集之后，并将确定的结果发送给接入网设备。
可选地，多个UE可以直接向接入网设备发送多个第五信息，而不通过核心网设备发送多个第九信息。
S840，接入网设备发送第七信息，该第七信息指示发送寻呼指示的时机在目标寻呼时机之前的第N个SS突发集之后。相应地，多个UE接收该第七信息。
作为一种可能的方式，接入网设备可以在系统消息中携带该第七信息，并且采用广播的方式发送该第七信息。

该过程可以参考S530中的方式1和方式2，在此不再赘述。
S860，多个UE中的每个UE根据第七信息，确定接入网设备发送PEI的时机。
S870，接入网设备在发送PEI的时机，发送PEI。相应地，多个UE在发送PEI的时机，监听PEI。
根据本申请的方案，网络设备可以根据多个UE上报的L值，确定发送寻呼指示的时机在目标寻呼时机之前的第N个SS突发集之后，并向多个UE发送确定的结果，从而达到更好地节省功耗的目的。
可选地，作为一种情况，该方法700可以在方法800之前执行。即，方法700与方法800之间并不是孤立的，二者可以结合在一起使用。此时，方法800中的多个UE包括方法700中的UE#1。
例如，当UE#1首次开机驻留到目标小区时，UE#1可以基于方法700监听PEI#1。后续，UE#1可以根据第七信息，确定接入网设备发送PEI的时机，基于该时机，监听PEI。
图9示出了本申请提出的另一种方法。
在介绍该方法之前，首先介绍UE获取UE所在的子组的标识(记为，UE subgroup ID)的方式：
方式1：
UE通过UE标识(UE_ID)确定UE subgroup ID。该UE_ID一般是由接入网分配的ID，例如该UE_ID可以是gNB分配的RNTI。
示例性地，UE subgroup ID＝UE_ID mod M。其中，mod表示取余数运算，M表示每个PO中的UE被分成的子组数。
方式2：
UE进入连接态后，核心网网元(例如，接入和移动管理功能(access and mobility management function，AMF)网元)向UE分配UE subgroup ID。
示例性地，AMF通过RAN向UE发送NAS信令，该NAS信令中包括UE subgroup ID。
图9所示的方法包括：
S901，RAN确定UE#1被寻呼。
其中，UE#1对应的PO为目标PO。
S902，RAN发送PEI#1。相应地，UE#1接收PEI#1。
该PEI#1关联至少一个PO，该至少一个PO中包括目标PO，目标PO对应PEI#1中的多个比特，该多个比特对应多个子组。示例性地，该多个比特中的每一比特分别指示所述多个子组中的每一个子组上是否存在寻呼。
示例性地，在未获取到UE#1所在的子组的标识的情况下，该多个比特中的至少一个比特指示存在寻呼。
作为一种实现方式，一个比特的值为“1”表示存在寻呼；一个比特的值为“0”表示不存在寻呼。换句话说，在未获取到UE#1所在的子组的标识的情况下，RAN将该多个比特中的至少一个比特设置为“1”。
假设，该多个比特为比特#1至比特#4：
示例性地，RAN可以在比特#1至比特#4中随机选择一个比特，将该比特的值设置为“1”。
示例性地，RAN可以固定地将比特#1至比特#4中的某一个比特设置为“1”。
示例性地，RAN可以根据尽可能降低虚警率的原则，从比特#1至比特#4中确定一个比特，将该比特的值设置为“1”。例如，RAN也可以尽量选择和上一次不同的比特来置1，以降低同一子组被虚警的概率。作为一种特殊情况，如果比特#1至比特#4中存在一比特指示的子组上存在寻呼，则RAN不需要再将其他比特的值由0置为1。
S903，UE#1确定UE#1对应的目标PO。
该目标PO对应PEI#1中的上述多个比特。
S904，作为第一种可能的情形，在UE#1未获取到UE#1所在的子组的标识的情况下，如果第一比特指示存在寻呼，则UE#1监听寻呼消息。该第一比特为上述多个比特中的任意一个比特。
换句话说，在UE#1未获取到UE#1所在的子组的标识的情况下，如果上述多个比特中的任意一个比特指示存在寻呼，则UE#1监听寻呼消息(监听寻呼消息是指在目标PO上监听寻呼PDCCH)。
作为第二种可能的情形，在UE#1未获取到UE#1所在的子组的标识的情况下，如果上述多个比特中的所有比特均指示不存在寻呼，则UE#1不监听寻呼消息。
下面通过几个例子介绍UE#1未获取到UE#1所在的子组的标识的情况。
例1：
UE#1还未进入连接态，核心网网元还不能向UE#1发送NAS信令。在此情况下，UE#1未获取到UE#1所在的子组的标识。但是RAN采用了基于核心网网元分配子组标识的方法来发送PEI。
例2：
UE#1只支持基于UE_ID的子组标识分配方法，但是RAN采用了基于核心网网元分配子组标识的方法来发送PEI。
例3：
UE#1并不支持PEI子组划分机制，但是RAN仍采用基于子组方式(PEI中的每个PO划分子组数大于1)来发送PEI。
示例性地，在S902之前，该方法还包括：
S905，RAN发送系统消息。相应地，UE#1接收该系统消息。
该系统消息中包括以下内容：
PEI#1的负载区大小(payload size)、PEI#1对应的PO是哪些、每个PO中的UE被分成的子组数。
UE可以根据该系统消息，确定目标PO对应比特数，以及目标PO对应的上述多个比特在PEI#1中的位置。
根据图9中的方法，当UE#1没有获取到UE subgroup ID时，UE仍然可以获知是否应该在自己的PO唤醒监听寻呼PDCCH，从而达到节省功耗的效果。
